2.3.2 Time Zone
-11 to 11
This parameter sets the time zone offset from UTC. Positive values are for time
zones west of UTC, and negative values are for time zones east of UTC. Set this
value to 0 to use UTC in the module.
2.3.3 Use Daylight Savings Time
Yes or No
This parameter specifies if daylight savings time will be used in the time
computation.
2.3.4 Database Register
-1 or 0 to 3992 as an even value
This parameter specifies if the NTP time computed by the driver is to be placed
into the module's database. If a value of -1 is specified, the time will not be
placed into the database. If the value is between 0 and 3992, the time will be
placed in the database. The first 4 bytes represent the seconds since 1/1/1970,
and the second 4 bytes represent the number of microseconds. An even value
should be used for the register value in order for the data to be stored correctly.
2.4 [EGD Exchanges]
In order to interface the module with EGD devices, you must construct an
exchange list. The exchanges specify messages that will be produced or
consumed at a user-defined frequency using the module's internal database.
Messages can be broadcast to all nodes on the network, sent to a multicast
group on the network or associated with a single node on the network. Up to 100
exchanges can be defined for the driver. Up to 680 word registers can be
produced or consumed in a single exchange.
The [EGD Exchanges] section defines the messages that will be produced and
consumed by the driver. The UDP protocol on the IP network is used to transport
these over Ethernet between all the EGD devices.
For the exchanges to operate correctly, the other EGD devices must be
configured and correctly set up. The primary reason for user problems with the
module is failure to provide devices that are correctly configured. Before trying to
connect the module to the network, the remote device must be able to
communicate with ProSoft Configuration Builder. You must understand and
document all parameters.
